Dear all, I’m writing you because I’m a bit confused about this, and at end I’m not sure at all if I need to flash or not, any ESP module, ESP-01, ESP8266, ESP32, in order to be able to use it, sending to it sketches from Arduino environment, as far as I know, if I try to use one of this devices directly from factory, I can only use AT commands, am I right?, at opposite, to flash it is like install in a new AVR device the “bootloader”, sorry for not to have too much experience on ESPs, not yet, I have a lot of theory, but when I’m treating to put it in practice I’m experiencing several problems, as it could be expected.
One more subject just to finish, what’s the best software to flash the units?, where to find it?
If you want to program the ESP boards using Arduino IDE, you just need to go to the Arduino IDE and upload the code. It’s that simple. You don’t need to install any previous firmware on the board.
Answering your last question, what do you mean by software to flash the units? Do you want to flash a binary file to the boards? esptool can be used. Learn more here: https://github.com/espressif/esptool
I hope this helps
Hi again Sara, same situtation, once i was able to comunicate i was discovered how to connect and upload sketches without any previous flashing process, thanks again for your help
